Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 5,281,715, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 5,281,715 | |
| -1 | -5,281,715 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,281,715.
Example:
1 x 5,281,715 = 5,281,715
and
-1 x -5,281,715 = 5,281,715
Notice both answers equal 5,281,715
With that explanation out of the way, let's continue. Next, we take the number 5,281,715 and divide it by 2:
5,281,715 ÷ 2 = 2,640,857.5
If the quotient is a whole number, then 2 and 2,640,857.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 5,281,715 | |
| -1 | -5,281,715 |
Now, we try dividing 5,281,715 by 3:
5,281,715 ÷ 3 = 1,760,571.6667
If the quotient is a whole number, then 3 and 1,760,571.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 5,281,715 | |
| -1 | -5,281,715 |
Let's try dividing by 4:
5,281,715 ÷ 4 = 1,320,428.75
If the quotient is a whole number, then 4 and 1,320,428.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 5,281,715 | |
| -1 | 5,281,715 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 53 | 95 | 265 | 1,007 | 1,049 | 5,035 | 5,245 | 19,931 | 55,597 | 99,655 | 277,985 | 1,056,343 | 5,281,715 |
| -1 | -5 | -19 | -53 | -95 | -265 | -1,007 | -1,049 | -5,035 | -5,245 | -19,931 | -55,597 | -99,655 | -277,985 | -1,056,343 | -5,281,715 |
